How to choose the right engine oil for your car: In regions with low winter temperatures, opt for engine oil with a smaller number before the 'W'; the opposite applies for high-temperature areas. The method for changing engine oil is as follows: 1. Lift the car, remove the underguard, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow for two minutes at the oil filler port, then tighten the oil drain plug and wipe it with a tissue to check for leaks; 3. Reinstall the underguard, lower the car, and use a funnel to add new engine oil through the filler port. The functions of engine oil include: lubrication, auxiliary cooling, cleaning, sealing to prevent leaks, rust and corrosion prevention, shock absorption, and wear resistance. Engine oils are categorized into mineral oil, semi-synthetic oil, and full synthetic oil.
Having driven for over a decade, my experience tells me that choosing engine oil should be straightforward and effective. First, check the vehicle manual—it recommends specific viscosity grades like 5W-30, so don’t guess blindly. In cold winters, opt for lower winter viscosity grades with a 'W,' such as 0W-20, to aid cold starts. For hot summers or older cars, use thicker oils like 10W-40. I prefer full synthetic oil—though pricier, it offers better engine protection, improves fuel efficiency at high speeds, and extends oil change intervals up to 10,000 km. Conventional mineral oil is cheaper and works for low-mileage cars, but avoid no-name brands that accelerate wear. Pay attention to oil change intervals and quantity: typically every 5,000 to 7,500 km, and regularly check the dipstick to ensure levels don’t drop below the minimum. When choosing brands, consider user reviews—popular and reliable options like Shell or Mobil are safe bets. Remember, engine oil is the lifeline of your engine—just pick what suits your car’s condition and avoid unnecessary tinkering.
